ROOF STRUCTURE.

Application filed November 3, 1921.

T0 all whom t may concern.' 4

Be it'lmown that I, CI-Iniu S. FREUND, a citizen oithe United States, residing at Chicago, in the county of Cook rand State of Illinois, have invented new and useful Improvements in vRoof Structures, of which the following isa-full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part 'ot this specification.

My invention relates toY 'root structures, and it has particular relation to structures of the 'charac-ter designated wherein light admitting members are positioned in the root and made a portion of the structure.

More particularly my invention contemplates the placing of slabs ofA corrugated glass in a roof structure in such manner that the entire root will be water-tight. To this end I position the tiles of the rootl and the glass slabs in overlapping relation, and it is further an object of my invention to combine the opaque tiles and the transparent or translucent glass slabs in such a manner that the yedges ot the slabs in each tier of the structure are so covered with a cap of tile or other material that the roof will be weatherproof, but will comprise relatively few parts.

In this connection I provide rollsl to cover the adjacent edges ot' `the slabs-#both the tile and glass-in suoli a manner that the above desirable structure may be formed. To further promote the durability and weather resisting qualities of my roof, I arrange the successive tiers of roofing members in progressively overlapping relation, and preferably cement the said overlapping edges together. Again, the adjacent edges of the slabs in successive tiers are `so positioned that they are staggered with respect to one another whereby the placing of the rolls .which make Vthe adjacent edges water-proofis facilitated. In this connection I provide the `tiles with recessed portions which are arranged to accommodate the rolls in the 'next tieroi tiles and, in this way, insure that the overlappingedges will be inoistureproof even at the points which have heretofore been the hardest to protect. Further, I 'provide particular tile support- Ling yinembers atthe overlappingredges-of the glass and tile 'slabs which facilitate the 'above described arrangement.

For a better understand-lng Jotmy 'inven- Serial No. 512,410.

F 9 is a longitudinal section thru the roll in this last modified form of roof; and,

Fig. l0 is a detail view of a the last mentioned roof.y

Referring now more particularly to the structure shown in Fig. l, trusses llll have a plurality of purlins 12-12 laid at right angles thereto, this structure comprising a foundation upon which the root tiles are laid. The tiles 18-13 are provided with lips or 'feet 13, which extend over the edge of the upper purlin as shown, and serve to support the tiles 13 when they are laid in a slanting position. A cap, formed oit tiles l4-14, is placed at the peak of the root. The tiles 13-13 are laid edge to edge and their adjacent edges are coveredy by rolls 15-15 whereby a water-tight tier is comprised.

In Fig. l the next tier of rooting members comprises a plurality of corrugated glass slabs y16 the adjacent edges of these portion of rslabs being covered by rolls 17. It will be noted that the rolls in the last Vmentioned tier are staggered with respect to the rolls l5 in the iirst described tier of tiles; that is, the junction of the edges of adjacent members in the two tiers are s'o staggered. `Each tile in the upper tier, however, 'is provided with a recessed semi-cylindrical portion 18 which extends over the rolls 1'? in the 'next lower tier of rooting members.

Til

The tiles 13 are cemented to the glass slabs, as shown, these all being in turn laid in cement on the purlins. The upper and lower ends of the glass slabs, however, rest respectively upon and are cemented to specially formed tiles 19 19, The tiles 19a have raised edge portions 2O2O, and are provided with a rolled recess 21. At the upper edge ot these tiles a foot 22 is provided which extends over the purlin and holds said special tiles in positionto receive the glass slabs. The advantage of this form of construction is quite marked since it is in certain cases impracticable to provide a supporting edge on the glass itself.

Extending between the two lowermost purlins is a tier of solid tiles 23S- 23, the latter being provided with lips 24- to secure them in place on the purlins, and it will be noted that the adjacent edges of these tiles have rolls 25-25 overlying the junction of said edges. It will further be noted that the tiles 19;L are positioned between the lower edges of the glass slabs and the upper edges of the tiles 23-23, and that the toot 22 secures these special tiles in this position, as shown. Moreover, the recessed semi-cylindrical portions 21 accommodate the upper ends oi: the rolls 25 whereby no opportunity is ai'orded for moisture to work down under the edge-protecting roll.

The glass is cemented to these tiles 19n and I iind it desirable to provide holes through the cement in the under corrugations in order that the moisture which condenses on the under side of the glass slabs may run down therethrough from the interior of the roof and be drawn otf together with the moisture which is deposited directly upon the upper surface of the root.

The manner in which the adjacent edges of the corrugated glass slabs are protected is best shown in Fig. 3. A metal strip 26 may be laid over the junction of these edges on cement, and then cement is applied on the top of the metal strips after which the roll or cap 17 is laid down. In Fig. 3 it will be noted that the recessed semi-cylindrical portion 18 of the upper tile 13 extends over and is cemented to the cap or roll 17. A longitudinal sectional view of the structure last described is shown in Fig. 6.

In Fig. 4 I have illustrated the manner in which the solid tiles and glass slabs may be combined in the second tier of the roofing structure to eventuate a roof having alternate "side-by-side glass and solid rooting slabs. The manner in which the adjacent edges of the dissimilar tile and of the glass slabs are protected in order to make the structure water-proof is shown in Fig. 5. A metal filler 27 may be laid down between the edges of the two dissimilar materials and then over this and the edge of the slabs cement is spread. The cap or rollk 1T is linally placed in position, as shown, and serves to adequately protect this point in the structure.

In describing the manner of placing the protecting rolls over the edges of the adjacent rolls I have referred to the use ot metal strips or iillers but it is to be understood that these are not always necessary and, in fact, I frequently lay the cement directly on the junction and place the roll thereover.

Referring now to Fig. S, I illustrate a modified form of rooting structure wherein a different character of interposing member is used in place of the special tile 19a. At their upper edges the glass slabs are laid directly upon the purlin withonly the interpositioning of a cord cushion 28 and at their lower ends they are cemented directly to the upper edge of the lower tier oi tiles 23. A. iashing 29 extends under the glass and up over the rolls as best shown in Fig. 9. These glass slabs may be laid down in oaku 1n instead of cement it such is desired. The positioning of the tiles as just described eventuates a very desirable water-tight root` structure and is very quickly and easily constructed. Here, again, holes may be left in the cement at the lower edge ot the glass slabs to permit the condensation on the under surface of the glass slabs to run oft.

IVhile I have shown but three embodiments ot my invention as utilized in a combined transparent and solid roofing struc4 ture, it is obvious that many modilications therein may occur to those skilled in the art, and I desire, therefore, that my invention be limited only by the showing of the prior art and by the scope ot the appended claims.

IVhat I now claim is new and desire to secure by Letters Patent of the 'United States is: v
